ATTORNEYS Patented June 14, 1932 UNITED STATES PATENT OFFICEFRITZ IBALZER, OF CINCINNATI, OHIO, ASSIGNOR TO THE AMERICAN LAUNDRY IA-CHIN ERY COHPANY,'OF. CINCINNATI, OHIO, A CORPORATION OF OHIO WASHINGMACHINE Application filed August 21, 1930. Serial No. 476,754.

My invention relates to fabric treating apparatus and particularly towashing and dr cleaning machine cylinders.

he present invention relates to cylinders having radial partitions forthe purpose of extending V shaped perforated portions for admittingwater or other cleaning liquid into the cylinder, one side of each Vshaped portion being formed bythe radial partitions and the other sidebeing formed by a sepa- L" rate member connected to the radialpartitions and to the cylinder sheet.

It is one object of this invention to provide a cylinder of suchconstruction that a load or batch of material in any compartment willoperate as a valve during the major part of the treating operation bylodging against the perforated areas to close the perforations andthereby trap the treating liquid in the compartment and cause it toremain with the load in the compartment to prolong the treatingoperation for substantially the entire distance of travel of thecompartment in a single rotation of the cylinder.

By such an arrangement, the batch or load in any one compartment isprogressively submerged in the liquid at the bottom of the cylinder, isthen spread out in the liquid in the cylinder permitting a penetrationof the treating liquid, and thereafter crowded with a squeezing actionin the presence of the trapped liquid in one corner of the treatingcompartment. Then, as the particular compartment continues to travel inits path around the central axis of the washing cylinder the batch islifted by a suitable baflie provided for that purpose and caused totumble into a pool in another corner pocket of the compartment wherefurther crowding and squeezing action is produced in the presence oftreating liquid. As the cylinder continues to rotate, the liquid fromthe compartment is discharged into the outer tub or casing and anadditional supply drawn in, the batch of materials being separated anddistributed through the new supply and being subjected to a sequence oftreatment steps as hereinbefore set forth. 7

Various other objects and advantageous features of my invention may beseen in the following description and one embodiment thereof may be seenin the accompanying drawings wherein similar characters of referencedesignate corresponding parts, and wherein:

Fig. 1 is a perspective view, partly broken away and partly in section,of awashing machine embodying my invention; Fig. 2 is a sectional Viewof the machine shown in Fig. 1; Fig. 3 is a detail view of theperforated V shaped inlet to and outlet from the washing machinecylinder; Fig. 4 is a sectional View showing a modified form of cylindercompartment structure; and Fig. 5 is a View similar to Fig. 4 showing astill further modified form of cylinder structure.

Referring to the drawings, I have shown a washing machine consisting ofthe usual tub or outer casing 1 supported on a suitable frame 2 andprovided with an upper opening 3 having a closure 4 and a lower opening5 having a closure member 6 that takes the form of apsliding apron.WVhen the machine is being unloaded, the closures 4: and 6 are openedwhereby the load from an inner rotatable container 7 can slide outthrough the lower opening 5 and into some form of conveying means ifdesired. However, the construction of the tub or cylinder 1, constitutesno part of the invention and may be of any desired form.

In accordance with my invention, the container or cylinder 7 which isrotatably mounted within the tub or outer casing 1 comprises end heads 8that are, in this instance, impcrforate although they might beotherwise. An outer cylindrical wall that is made up of sections issecured to the end heads 8 in any desired manner and one edge of eachsection is secured to the outer edge of a radial par- 10 that is more orless of yramid form and coextensive with the lengt of the partition towhich it is attached. Such baflles are arranged on the partitions eadjacent to but sliightly separated from the center of-the cylin er atwhich point the partitions join and serve the purpose of retardi orholding back the work within the cylin er so that mstea' d of simplysliding outwardly along the partition uring rotation of the cylinder thework is tumbled so that all arts thereof come in contact with thetreatmg fluid at sometime during the washing or cleaning operation,during which time the work is retained in the cyhnder. While each coment is provided with but one of the aflles, nevertheless this batfleacts in practically the same manner in both directions of rotation ofthe cylinder.

It will be noted that the partitions 9 adjacent their point ofconnection with the edges of the sections which go to make u the innercylinder wall are perforated an that perforated plates 11 extendangularly 25 outwardly from the partitions 9 and from a point at whichthe perforated portions of the partitionsend, these plates havin theirouter edges secured to the opposite as of the sections which make up theouter cy der wall. The rforated portions of the partitions 9 an theangularly extending plates 11 form V shaped openings by way of whichliqm'ld within any one complartment in the cy der may travel outwar yinto the tub or outer casing or liquid from the tub or outer casing mayenter the compartment. f

For convenience and as is usual'in cylinder construction, the cylinderis provided with doors 12 and 13, the only difierence being that eachcom artment in this instance is rovided with suc doors whereby work mayplaced within each compartment or removed therefrom.

In the operation of'this device,;the work in any one compartment issubjected to several crowding, squeezing and separating o rations in thebath of treating 'quid whic results in several separate penetratingefi'ecte tion. The crow ing and squeezi action is brought about by thework tum into the corner of the compartment which 18 first lowered, deupon the direction of rotation of e cyhnder wheieb the weight of thework and the centrifug'zl force tends to extract the treating 1i uiderefrom. At the same time, the wor by covering the perforated portion ofthe corner, acts as a valve or closure for the perforations and asprevents the escape of treatinslliquid from the compartment throughoutor at least the greater portion, of the rotation of the glinder, wherebythe work is subjected to V e same treating liquid a number of times.- Bythe use of partitions that are imperof the treating li uid throughoutone revolu- 1,eea,eea

forate throughout their greater portion and the action of the work onthe perforated portion, liquid from any one compartment ma not easilyenter another com artment to us carry undesirable materials om onecompartment into another. However, liquid from any compartment maydischar into the outer tub or casin at certain points in the rotation ofthe cyhnder and the undesirable material be allowed to settle into or begathered in traps such as are normally used with washing machines ofthis type. Likewise, treating liquid from the outer tub or casing willhaveample time to enter the compartment whereby the work therein may besullageected to a fresh supply.

ferring to Figures 4 and 5 of the drawings, I have shown modified formsof cylinders wherein the partitions are so connected at their ad'acented or so formed that the angle of t e artitlon will be increased so asto more e ciently unload the machine through the lower a ron or door 6of the outer tub or casing. n Fig. 4 the ad'acent edges of the partition9 are so connec as to form atriangular space 14 while .in Fig. 5 thepartitions are bent near their adjacent edges so as to increase theangularity of the greater portion of the partitions.

With the construction shown a cylinder is provided in which workis sujected to a series of crowding, tumbling and squeezing actions duringone rotation of thecylinder whereby the work is more eflicientl cleanedwith a lesser amount of treating stead of being merely rolled over andover as it would be in the usual perforated cylinder having no partionsor .bafies therein.
